Introduction
Ensure that you read the following safeguards when
setting up your projector.
Caution concerning the lamp unit
■ Potential hazard of glass
particles if lamp ruptures.
In case of lamp rupture,
contact your nearest
Sharp Authorized Ser-
vice Center or Dealer for
a replacement.
See “Replacing the Lamp” on page 56.
Caution concerning the setup of the pro-
jector
■ For minimal servicing and to maintain high
image quality, SHARP recommends that this
projector be installed in an area free from hu-
midity, dust and cigarette smoke. When the
projector is subjected to these environments,
the vents and lens must be cleaned more of-
ten. As long as the projector is regularly
cleaned, use in these environments will not
reduce the overall operation life of the unit.
Internal cleaning should only be performed
by a Sharp Authorized Service Center or
Dealer.
Do not set up the projector in places ex-
posed to direct sunlight or bright light.
■ Position the screen so that it is not in direct
sunlight or room light. Light falling directly on
the screen washes out the colors, making
viewing difficult. Close the curtains and dim
the lights when setting up the screen in a
sunny or bright room.
The projector may be safely tilted to a
maximum angle of 12 degrees.
■ Placement should be within ±12 degrees of
horizontal.
Warning about placing the projector in
a high position
■ When placing the projector in a high posi-
tion, ensure to secure it carefully to avoid
personal injury caused by the projector fall-
ing down.
Do not subject the projector to hard im-
pact and/or vibration.
■ Take care with the lens so as not to hit or
damage the surface of the lens.
Rest your eyes occasionally.
■ Continuously watching the screen for long
hours will cause eye strain. Ensure to occa-
sionally rest your eyes.
Avoid locations with extremes of tem-
perature.
■ The operating temperature of the projector
is from 41°F to 95°F (+5°C to +35°C).
■ The storage temperature of the projector is
from –4°F to 140°F (–20°C to +60°C).
Do not block the exhaust and intake
vents.
■ Allow at least 7
7 /
8
inches (20 cm) of space
between the exhaust vent and the nearest
wall or obstruction.
■ Ensure that the intake vent and the exhaust
vent are not obstructed.
■ If the cooling fan becomes obstructed, a pro-
tection circuit will automatically put the pro-
jector into standby mode to prevent overheat
damage. This does not indicate a malfunc-
tion (See pages 54 and 55.). Remove the pro-
jector power cord from the wall outlet and wait
at least 10 minutes. Place the projector where
the intake and exhaust vents are not blocked,
plug the power cord back in and turn on the
projector. This will return the projector to the
normal operating condition.
